Definition of Stainless Steel Plate
1. Stainless Steel Plate is generally stainless steel plate and acid-resistant steel plate. Coming out at the beginning of this century, the development of stainless steel plate for the development of modern industry and scientific and technological progress has laid an important material and technological foundation.
2. Stainless steel plate refers to the corrosion resistance of weak medium such as atmosphere, steam and water steel plate, and acid resistant steel plate refers to the corrosion resistance of chemical etched medium such as acid, alkali, salt steel plate. Stainless steel plate since the beginning of the 20th century, has a history of more than 1 century.
3. The stainless steel plate has a smooth surface, high plasticity, toughness and mechanical strength, and is resistant to acid and alkaline gases. Corrosion of solution and other media, it is not easy to rust alloy steel, but it is not absolutely rust free.
Different, it has gradually formed several categories in the development process. According to the structure, it can be divided into four categories: austenitic stainless steel plate, martensitic stainless steel plate (including precipitation hardening stainless steel plate), ferritic stainless steel plate, and austenitic ferritic duplex stainless steel plate.
Features of stainless steel plate
1. Stainless steel plate is generally stainless steel plate and acid-resistant steel plate. Coming out at the beginning of this century, the development of stainless steel plate for the development of modern industry and scientific and technological progress has laid an important material and technological foundation.
2. Stainless steel plate has high temperature oxidation resistance, and all stainless steel plates have high temperature oxidation resistance. However, the oxidation rate will be affected by inherent factors such as exposure environment and product form.
3. The stainless steel plate has a smooth surface, high plasticity, toughness and mechanical strength, and is resistant to acid, alkaline gas, solution and other media. It is an alloy steel that is not easy to rust, but it is not absolutely rust free.
Stainless steel plate is a kind of alloy steel that is not easy to rust. Stainless steel plate has many characteristics such as corrosion resistance, high temperature oxidation resistance, and smooth surface.

Classification of stainless steel plates
Classification by thickness | It can be divided into: thin plate (0.2mm-4mm), medium plate (4mm-20mm), thick plate (20mm-60mm) and extra thick plate (60-115mm). |
Classification according to production mode | It can be divided into: hot rolled steel plate (steel plate formed by heating furnace), cold rolled steel plate (steel plate produced by cold rolling process). |
Classification by use | It can be divided into: bridge steel plate, boiler steel plate, shipbuilding steel plate, armor steel plate, automobile steel plate, roof steel plate, structural steel plate, electrical steel plate (silicon steel sheet), spring steel plate, and solar energy special plate (HIRUIT steel). |
Classification according to steel structure | It can be divided into austenitic (200 series and 300 series stainless steels), austenitic ferritic (both austenitic and ferritic stainless steels), ferritic (409, 430, 434 series stainless steels) and martensitic (403, 410, 414, 416,) |
Classification according to surface characteristics | It can be divided into: silver white matt (no need for surface gloss), bright as a mirror (building materials, kitchen appliances), rough grinding/intermediate grinding/fine grinding/extremely fine grinding (building materials, kitchen appliances), hair grain grinding (buildings, building materials), near mirror grinding (for art, decoration), mirror grinding (reflector, decoration). |
